i have a ktm 125 sx motorcross and i think for every 5 litres of petrol i use 250ml of oil i think can anybody please confirm this 4 me thank u, i havent rode it in a while and i have bad memory lol, jim,
My son locked up two cranks on Hondas using 40/1, he had a new 125sx in 04 and changed to 32/1......raced all season with no trouble....co-incidence ?......maybe
Oil is dear enough but a lot cheaper than rebuilds
regards
